Provided herein are methods of preparing tetrahexahedra nanoparticles and methods of using the tetrahexahedra nanoparticles as an oxidative catalyst.

Provided herein are methods of preparing tetrahexahedra nanoparticles and methods of using the tetrahexahedra nanoparticles as an oxidative catalyst.

Provided are a composite in which metal nanoparticles are evenly dispersed and adsorbed to pores of a support, and a method of preparing the same. An amorphous nanostructure formed of inorganic polymers having a transition metal and a halogen element as a main chain via hydrogen bonding is used as a chemical template for forming the metal nanoparticles. The formed metal nanoparticles are evenly dispersed and adsorbed to the support with pores.

Methods and systems for manufacturing a mixed-metal part by preparing a mixed-metal sol-gel as a feed material and using an additive manufacturing technique to form the mixed-metal part from the mixed-metal sol-gel feed material.

A powder bed material can include from 80 wt % to 100 wt % metal particles having a D50 particle size distribution value from 4 μm to 150 μm. From 10 wt % to 100 wt % of the metal particles can be surface-activated metal particles having in intact inner volume and an outer volume with structural defects. The structural defects can exhibit an average surface grain density of 50,000 to 5,000,000 per mm.sup.2.
